The three correct ways in which heat energy leaves the surface of land masses are:
- Radiation of infrared energy - Heat is emitted in the form of infrared radiation from the surface.
- Evaporation - The process of water evaporating from the surface absorbs heat, effectively removing energy from the land.
- Conduction to air, which then rises in convection - Heat is transferred from the land surface to the air above it, and this warm air can then rise, carrying heat away from the surface.
The other options, such as glacial motion, plant growth, and animal activity, do not directly reference the processes through which heat energy leaves the surface of land masses.
